This application July 24, 1945, Serial No. 606,837

3 Claims.

This invention relates to new and useful improvements in a closure for a container cover.

This is a substitute for my original application filed November 1, 1943, Serial Number 508,475.

More specifically, the invention contemplates the construction of a closure for a container cover, which is characterized by an annular skirt wall for engagement on said container, and a transverse wall mounted across said skirt wall and positioned slightly downwards from the top edge of said skirt wall and being formed with an opening closable with an improved closure member.

It is proposed that the improved closure member be rested upon the'top face of said transverse wall and be adapted to move from a position over said opening to a position to one side of the opening.

It is proposed that said skirt wall be provided with bayonet slots or openings formed on the opposite sides of said cover and above said transverse wall. It is proposed that a string or strings extend vfrom the opposite sides of said closure member and through said bayonet slots whereby said strings may be manipulated to move said closure member partly or fully off or on said opening. It is further proposed to manipulate said strings in said bayonet slots or openings for frictionally holding said closure member in a stationary selected position.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are mor particularly set forth.

In the accompanying drawings forming a material part of this disclosure-- Fig. 1 is a perspective view of a container with a cover having a closure constructed in accordance with this invention.

Fig. 2 is a plan view of Fig. 1 but illustrated with the closure member in an open position.

Fig. 3 is a fragmentary vertical sectional view taken on the line 33 of Fig. 1.

Fig. 4 is a fragmentary enlarged sectional view taken on the line 4-4 of Fig. 1.

Fig. 5 is a side elevational view of a container of a modified form provided with a cover constructed in accordance with this invention.

The cover for a container ID, in accordance with this invention, includes a skirt wall II for engagement upon the top of said container Ill. The skirt wall I I has a beaded upper edge II provided with a groove Il disposed around its inner periphery, and a transverse wall I2 is mounted across said skirt wall and positioned slightly downward from the top edge of the skirt wall II with its peripheral edges engaging the groove II and formed with an opening I3. A closure member I4 rests on the top face of the transverse wall I2 and is adapted to close said opening I3. The skirt wall is formed of spaced wall portions forming a channel into which the top edge portion of the container ID extends, see Fig. 3.

The skirt wall It is formed with bayonet slots I5 having large ends I6, and small ends I! directed outwards. These bayonet slots I5 are formed in opposite sides of the top portion of the skirt wall II and on a level with the top of the transverse wall l2. A string I8 has loop portions extending from opposite sides of said closure member I4 and through the large ends l6 of said bayonet slots I5. As illustrated, the string I8 is formed from a length of string hav-'- ing its ends tied together into a knot I9. Intermediate portions of the continuous length of string are engaged through holes 20 formed in the closure member I4 by which the closure member I4 is rigidly attached on portions of said string.

The string. I8 has a loop portion extended forward and a loop portion extended rearwards'. The forwardly extending loop portion is en'- gaged through a spaced pair of said bayonet slots I5 on the front side of the skirt wall II and the back loop is engaged through spaced bayonet slots I5 at the back side of the skirt wall II. Each bayonet slot I5 has a slot 2| extended inwards from the top edge of the skirt wall I I of the cover through which the string I8 may be slipped into and removed from the bayonet slots, as desired.

In Fig. l the string It is shown passing through the large ends I 6 of the bayonet slots I5. The closure member I4 is shown engaged over and closing the opening I3. In this condition the back loop of the string I3 may be pulled for moving the closure member l4 into an open position, as illustrated in Fig. 2. When it is desired to close the opening I3 it is merely necessary to pull the front loop of the string I8 to a position as illustrated in Fig. 1. The knot I9 facilitates gripping the back loop of the string I8 by which it may be easily pulled. A button or knot 22 is formed centrally on the front loop by which the front loop of said string or strips I8 may be easily gripped and pulled.

The closure member 14 may be releasably held in a stationary position closing the openin 13 or partially closing said opening, or in an open position, merely by forcing the side portions of the loops of string l8 into the small ends I! of the bayonet slots. The dot and dash lines l8 in Fig. 4 illustrate the new position of the string l8. In the new positions the top and bottom edges of the small ends of the bayonet slots l5 grip and hold the string I8 and so indirectly hold the closure H as selected.

In Fig. 5 another embodiment of the invention is shown in which the new cover is applied to a container [0 having a side handle 24. This container I0 is provided with a cover constructed identically as disclosed in Figs. 1 to 4. In other respects this form of the invention is identical to the previous form and like parts are indicated by like reference numerals.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. In combination with a cover for a container having a transverse wall surrounded by a skirt wall having a portion projected above the top face of the transverse wall and formed with an opening in one side thereof adjacent the skirt wall, means for closing the opening in the transverse wall, comprising a closure member rested on the top face of the transverse wall and of a size greater than the opening, the portion of the skirt wall projected above the transverse wall being formed on opposite sides of the opening with opposed pairs of slots on a level with the top face of said closure member, and a continuous string having loop portions extending from the top face of said closure member on opposide sides thereof, said loop portions being slidably extended through said opposed pairs of slots to be pulled in one direction to position said closure member over the opening or in the opposite direction to position said closure member on the top face of the transverse wall to one side of the opening.

2. In combination with a cover for a container having a transverse wall surrounded by a skirt wall having a portion projected above the top face of the transverse wall and formed with an opening in one side thereof adjacent the skirt wall, means for closing the opening in the transverse wall, comprising a closure member rested on the top face of the transverse wall and of a size greater than the opening, the portion of the skirt wall projected above the transverse wall being formed on opposite sides of the opening with opposed pairs of slots on a level with the top face of said closure member, and a continuous string having loop portions extending from the top face of said closure member on opposite sides thereof, said loop portions being slidably extended through said opposed pairs of slots to be pulled in one direction to position said closure member over the opening or in the opposite direction to position said closure member on the top face of the transverse wall to one side of the opening, said slots having large ends through which said loop portions freely slide and small ends into which said loop portions may be forced to frictionally hold the string with said closure member ineither of its two positions.

3. In combination with a cover for a container having a transverse wall surrounded by a skirt wall having a portion projected above the top face of the transverse wall and formed with an opening in one side thereof adjacent the skirt wall, means for closing the opening in the transverse wall, comprising a closure member rested on the top face of the transverse wall and of a size greater than the opening, the portion of the skirt wall projected above the transverse wall being formed on opposite sides of the opening with opposed pairs of slots on a level with the top face of said closure member, and a continuous string having loop portions extending from the top face of said closure member on opposite sides thereof, said loop portions being slidably extended through said opposed pairs of slots to be pulled in one direction to position said closure member over the opening or in the opposite direction to position said closure member on the top face of the transverse wall to one side of the opening, said slots having large ends through which said loop portions freely slide and small ends into which said loop portions may be forced to frictionally hold the string with said closure member in either of its two positions, said skirt wall being formed with narrow slots leading from the top edge of the skirt wall to said pairs of slots through which the loop portions of said string may be passed to be engaged with and disengaged from said pairs of slots.
